I live in NE Ohio and have a small-ish (17x34) workshop attached to the back of my garage. I have insulated the walls and ceiling with batt fiberglass insulation backed with kraft paper. However, I have not put a treatment on the ceiling. My intention is to use ribbed barn siding.
My question is, should I put a vapor barrier over the insulation before installing the ceiling? I've seen competing answers on social media (because everyone there is an expert).
But what I don't want is condensation building up between the vapor barrier and the steel ceiling, causing eventual rust issues. If I were using drywall, I'd probably say yes, since it will be on the warm side. It's the steel that has me questioning the proper course of action.
